Intralymphatic immunotherapy (ILIT) has been used successfully in both human and veterinary medicine as a safe and effective treatment for allergic diseases. Initially, ILIT was administered by ultrasound guidance, but palpation-based injections have become more popular among veterinary dermatologists. Data from human medicine, however, show that precise injection into the lymph node is mandatory, and injection quality clearly correlates with clinical response.

Objective: To study the development of allergen-blocking immunoglobulin (Ig)G in dogs injected with Der f 2-carrying enveloped plant-based bioparticles (eBPs).
Materials And Methods: Laboratory beagle dogs were injected intradermally (ID) or subcutaneously (SC) with Der f 2-eBP three times at 2-week intervals.
Background: Immunoglobulin (Ig)E cross-reactivity has been shown between Dermatophagoides farinae (Df; house dust mite) and the nematode Toxocara canis (Tc), yet its allergen basis is unknown.
Objectives: To identify the Df allergens IgE-cross-reactive with those of Tc.
Animals: Archived sera from 73 dogs with suspected allergy sensitised to Df.
Canine atopic dermatitis (CAD) is an allergic, inflammatory, and pruritic skin disease associated with the production of IgE antibodies against environmental allergens and mainly house dust mite allergens. This complex dermatological pathology involves Interleukin 31 (IL-31) as a central itch mediator. One of the most effective CAD treatments is a caninized monoclonal antibody (mAb) called Lokivetmab.

Hymenoptera venom specific immunotherapy (VIT), the only disease-modifying treatment, has the potential to prevent future life-threatening reactions in human patients. Prospective clinical data on VIT efficacy in dogs are currently lacking.

However, there is little known about the function of these cytokines in atopic dogs. This study compared the plasma levels of IL-10 and TGF-ß1 in atopic and control dogs and investigated their changes during different ASIT approaches.
View Article and Find Full Text PDFBackground: Canine atopic dermatitis (cAD) is a common chronic relapsing pruritic skin disease for which management commonly relies on life-long use of immunomodulatory drugs. A number of the medications used are associated with adverse effects and the potential for complications during long-term use.
Hypothesis: The goal of the study was to determine if a complete and balanced diet formulated for therapeutic benefit could contribute towards management of cAD.
There is growing evidence that equine papillomavirus type 2 (EcPV2) infection is etiologically associated with the development of genital squamous cell carcinoma (SCC) and precursor lesions in equids. However, the precise mechanisms underlying neoplastic progression remain unknown. To allow the study of EcPV2-induced carcinogenesis, we aimed to establish a primary equine cell culture model of EcPV2 infection.

Our aim was to use the best available evidence to construct and then to validate a medication score (MS) formula that will estimate the impact of concurrent medications on trial outcomes.
Methods: Trials of 15 interventions were scrutinized to find those that were consistent in terms of specific medication, administration route and dosage regimen.
Background: The gold standard to diagnose food allergy in dogs is an eight week elimination diet trial (EDT) followed by a re-challenge. A recent study demonstrated that a shorter EDT is possible if prednisolone is administered initially.
Hypothesis/objectives: The goal was to evaluate the sensitivity and specificity of the EDT based on the number of relapses after prednisolone discontinuation.
Background: Regulatory T (Treg) cells are involved in homeostasis of immune regulation and suppression of inflammation and T-cell polarisation. Current knowledge regarding the role of Treg cells in the initiation of allergic disease is limited for both people and dogs.
Objectives: To explore the role of circulating Treg cells and their possible influencing factors, on the development of atopic dermatitis (AD).
In this pilot study, we wished to determine if C-reactive protein (CRP) levels could be a useful severity or treatment biomarker for canine atopic dermatitis (AD). Nine atopic dogs received allergen immunotherapy for 1 year. Blood was collected before and at four re-evaluation visits.

Hypothesis/objectives: The present study compared the efficacy and safety of subcutaneous (SCIT), intralymphatic (ILIT) and sublingual (SLIT) immunotherapy.
Background: There is accumulating evidence in studies of allergic diseases in humans and dogs that environmental experiences during the first months of life can influence the development of allergic disease. No prospective study has evaluated this in veterinary medicine.
Hypothesis/objectives: To assess early-life risk factors for canine atopic dermatitis (cAD) and estimate its heritability.
Canine atopic dermatitis (CAD) is a prevalent inflammatory skin disease of dogs worldwide. Certain breeds such as the West Highland White Terriers (WHWT) are predisposed to suffer from CAD. Microbial dysbiosis is known to play a significant role in the pathogenesis of the disease, which is similar to its human counterpart, atopic dermatitis (AD).
View Article and Find Full Text PDFBackground: Canine atopic dermatitis (cAD) is a common allergic skin disease that is known to affect individuals early in life; the natural history of its initial development has not been documented. Some breeds such as West Highland white terriers (WHWTs) are highly predisposed to cAD.
Objectives: To follow 100 WHWT puppies during their first three years and to record the onset of clinical signs of cAD.
Background: There is growing evidence that equine papillomavirus type 2 (EcPV2) infection is causally associated with the development of equine genital squamous cell carcinomas (SCCs). Early stages of disease present clinically as plaques or wart-like lesions which can gradually progress to tumoural lesions. Histologically these lesions are inconsistently described as benign hyperplasia, papilloma, penile intraepithelial neoplasia (PIN), carcinoma in situ (CIS) or SCC.
